Booster vs Zetta Link

A rule-based proxy client for iPhone and iPad. It uses the system VPN to capture traffic on the device and send it direct, through a proxy, or to a block rule — depending on your configuration. The app does not sell or host any servers; you bring your own nodes and rules. Capture HTTP, HTTPS, and TCP traffic from apps on the device and send it to the selected proxy. Works on Wi-Fi and cellular. Inspect recent connections, live speed, and traffic usage. Match rules by domain, domain suffix, domain keyword, CIDR, and GeoIP. Test rules before you rely on them. Import rule files from a URL or Files (including iCloud Drive). Add nodes from subscription URLs, share links, or QR codes; refresh subscriptions on launch. Auto-select and fallback groups, plus latency tests. Block ads and trackers by domain. Local DNS / Hosts mapping. DNS over HTTPS. HTTP URL, header, and body rewrite, plus Map Local. Extra routing lines from the Script section of a profile. Optional IPv6; UDP forwarding can be turned on or off. Simplified Chinese, Traditional Chinese, English, Japanese, Korean, and Russian. VPN access is used only to route traffic according to the rules you configure. Please note: Booster is a standalone networking utility and does not include any proxy services or server resources. Users are responsible for providing their own configurations.

Zetta routes your iPhone's traffic through the proxy servers in your subscription, following the rules you set. SUBSCRIPTIONS • Paste a subscription URL and Zetta parses the server list. • Keep several subscriptions and switch between them with a tap. • Each subscription can refresh on its own schedule. ROUTING • Rule mode sends mainland China domains and IPs direct and everything else through the server. Global mode sends everything through the server. • Add your own rules: domain, domain suffix, keyword, IP range. • Type a domain to see which rule it would hit before you connect. CONNECTION • Live upload and download speed, connection time, and the last 60 seconds as a chart. • Test server latency before connecting. • A widget on the Home Screen and Lock Screen shows the connection state. • Siri and Shortcuts: "Turn on Zetta", "Zetta connect to Tokyo 01". PRIVACY • No account and no sign-up. Subscription URLs stay on your device. • Zetta has no servers of its own and sends nothing anywhere except to the servers in your subscription. Zetta needs a subscription from a proxy provider. It does not include one.
